For me it sounds like to much paste. If it worked in former runs with the same design and stencil look for changes in your printing process, check the volume and shape of your deposit. Redesigning pads and playing with aperture size allowing for mor

Folk's, I'm looking for some helpful suggestions for reworking wave soldered bottomside components that have been glued. I'm not a fan of the twist and break approach and as some of them either have a double dot or a slot configuration this tend's t

We now put soldermask on copper and then immersion nickel/gold plate our fine line boards. One of our vendors says this causes skipped plating in small via holes and wants to nickel/gold plate the whole board, including via holes, and then apply sold

Contact the fabricator of this part for their recommendations. There is about as many different approaches to soldering thermistors as there is thermistors. You imply that this is a SMT style package. If that is correct, it's curious that the comp

I was approached by the comp. suplier to change the capacitors that I currently used. No change in elect. charateristic, but only on : a) change of palladium to nickel base inner electrode b) outer electrode material i.e. from silver to copper. Que
